RNA polymerase II acts as an RNA-dependent RNA polymerase to extend and destabilize a non-coding RNA.

RNA polymerase II (Pol II) is a well-characterized DNA-dependent RNA polymerase, which has also been reported to have RNA-dependent RNA polymerase (RdRP) activity. Natural cellular RNA substrates of mammalian Pol II, however, have not been identified and the cellular function of the Pol II RdRP activity is unknown. We found that Pol II can use a non-coding RNA, B2 RNA, as both a substrate and a...

Enhancement of RNA Interference Effect in P19 EC Cells by an RNA-dependent RNA Polymerase

Background: RNA interference (RNAi) is a phenomenon uses double-stranded RNA (dsRNA) to specifically inhibit gene expression. The non-specific silencing caused by interferon response to dsRNA in mammalian cells limits the potential of utilizing RNAi to study gene function. Duplexes of 21-nucleotide short interfering dsRNA (siRNA) inhibit gene expression by RNAi. In some organisms, siRNA can als...

RNA helicase A acts as a bridging factor linking nuclear beta-actin with RNA polymerase II.

Actin, the major component of the cytoplasmic skeleton, has been shown to exist in the nucleus. Nuclear actin functions in several steps of the transcription process, including chromatin remodelling and transcription initiation and elongation. However, as a part of PICs (pre-initiation complexes), the role of actin remains to be elucidated. In the present study, we identified RHA (RNA helicase ...

RNA-dependent RNA polymerase of tobacco plants.

Several properties of RNA polymerase (nucleosidetriphosphate:RNA nucleotidyltransferase, EC 2.7.7.6) active fractions obtained from tobacco plants, be they uninfected, infected with tobacco mosaic virus, or infected with tobacco necrosis virus, were compared. By the seven criteria tested, the RNA-dependent RNA polymerase from these three sources behaved the same, although its activity is greatl...
